SHIVE-EXTRACTOR FOR CARDING-IVIACHINES.

SPECIFICATION forming part of Letters Patent No. 457,512, dated August 11, 1891.

Application led March 9, 1891.

To all whom it may concern.-

Be it known that we, FURGUS OSWAL GRovEs and HENRY HUNT GRovEs, of N ewton, (Lower Falls,) in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Shire-Extractors for Carding-Machines, of which the following is a specification. The invention has relation to carding machinos or engines; and it has for its object the provision of means whereby the fragments of burrs or shives which were not taken out by the burring-machine or rst breaker may be removed before the staple passes into the finishing-machine.

As is Well known, it is quite impossible to remove all the vegetable matter from burr wool before the staple is made up into cloth with machines as at present constructed, and it is necessary to expend a great deal of labor in burling the goods before the same are considered suitable for the market. By the present invention the work last mentioned is obviated, we having discovered that by reciprocating a comb or serrated blade in lcontact with the surface of the tumbler of the finishing carding-machine such burrs or shives as have not been removed by the barring-machine or iirst breaker may readily be knocked o or combed out of the wool before being passed to the carding-cylinder.

The invention consists of one or more reciprocating combs arranged to operate upon the face of the tumbler-preferably, though not necessarily, below the tumbler-so as to comb or knock out the fragment-s of burrs, shives, or other vegetable matter which may remain in the wool when the same is fed to the tumbler by the licker-in.

Reference is to be had to the annexed drawings, and to the letters of reference marked thereon, forming a part of the specication, the same letters designating the same parts or features, as the case may be, wherever they occur.

Of the said drawings, Figure 1 is a vertical sectional'view of so much of a carding-engine as is necessary to illustrate the invention. Fig. 2 is a perspective view, drawn to an enlarged scale, of the reciprocating combs or Serial No. 384,226. (No model.)

blades employed to remove the burrs or shives from the staple upon the tumbler.

In the drawings, a designates the cardingcylinder. b designates the feeding-apron employed to convey the wool to the feed-rolls c c, by which it is taken and delivered to the licker-in d, which passes it to the tumbler e, whence it is passed or licked into the carding-cylinder ct and operated upon by the strippers f and workers g.

The parts thus far described may be of usual construction and constitute no part of my invention, except in so far as the tumbler e co-operates with the Vmedium comprising our improvement, whereby the burrs or shives are removed from the wool.

The essential element of our improvement consists of a reciprocating comb adapted to operate in contact with the surface of the tumbler e. This comb may be constructed in various forms and operated by various means, and in some instances it may be found expedient to employtwo or more combs to operate as before mentioned.

As herein shown, the combs h consist of blades of metal having serrated or saw-toothed edges z'. These combs are mounted upon bars j, which bars are secured at their ends to the outer portions of quadrants or spiders la, which are at their inner ends or centers hung upon the journal-shaft Z of the tumbler e. At the lower end or circumference of one of the quadrants lo there is an ear m, in which is pivoted one end of a rodtor pitman fn, the opposite end of which i/sjournaled upon a Wrist-pin o, connected with a rotating disk p, so that in the operation of the machine the quadrant k may be vibrated or reciprocated to receprocate the combs h in contact with the surface of the tumbler e, which operation will effect the removal of burrs, shives, and other vegetable matter from the staple in the tumbler before the saine passes to the carding-cylinder. The disk p may be rotated by means of a belt and pulleys (not shown) from the shaft of the worker g, though sometimes I have extended the pitman n toward the feeding-apron and provided the shaft of the disk p with a gear, which was driven by a gear on the shaft of the lower feed-roll c. Other suitable means IDO may, however, be provided for reciprocating the combs.

We have herein represented three combs or blades as arranged to operate in contact with the tumbler; but, as before stated, a single comb or two or three or more may be employed, as circumstances may require.

XVe have found from experience that the burrs or shives which have not been removed by the first breaker or burring devices will lie upon the surface of the wool upon the tumbler and more readily be removed by Va reciprocating comb such as we have described, so that the staple may pass to the finishingcards quite free from vegetable matter.

The reciprocating motion imparted to the combs is an important feature of the invention, since it not infrequently happens that shives, straws, burrs, dac., are caught on the points of the comb-teeth and would remain there lodged were it not for the movement of the comb against the direction of motionof the card-teeth of the tumbler, which serves to free the teeth of the comb from foreign substance, which is knocked o upon the floor or into a receptacle.

By placing the reciprocating combs below the tumbler, as represented in the drawings, the vegetable matter combed or knocked out by the said combs may be allowed to fall upon the door or into any'suitable receptacle beneath the tumbler, though the said combs might be made to operate at other points upon the tumbler than directly beneath the same, and any suitable means may be employed for reciprocating the same. Hence we do not confine ourselves to the precise form and arrangement of parts herein shown.

Having thus explained the nature of the invention and described one of the ways of constructing and using the same, though without attempting to describe all of the forms in which the device may' be made, we declare that what We claim is l. The combination, with the tumbler of a carding-machine, of a comb and means for reciprocating or vibrating it, the said comb being constructed and arranged to operate upon the surface of the tumbler to knock olf or remove the shives or burrs from the staple, as set forth,

2. The combination, Vwith the tumbler of a carding-machine, of a plurality of vibrating combs or blades having serrated or sawtoothed edges constructed and arranged to operate upon the surface of the tumbler, and means for actuating the combs, as set forth.

3. The combination, with the tumbler of a v carding-machine and its journal-shaft, of quadrants or spiders hung upon said journalshaft, and a comb and means for reciprocating or vibrating it, the said comb being supported by the said segments and arranged to operate upon the surface of the tumbler, as set forth.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, this 14th day of February, A. D. 1891.
